Audacity does not recognise my audacity file

I was editing a recording when my pc crashed. When I rebooted computer an error shows stating that Audacity does not recognise the file tbp june.aup and suggests I try importing raw data. The recording is 6 hours long so creates hundreds of different files when I do. Advise would be very much appreciated as this is a great one-off recording. Thanks

You need to pay serious attention to fixing the crash which is probably due to your sound card or its drivers. Otherwise it may keep happening. See

Use the Automatic Crash Recovery dialogue if that appears:

If you have no choice but to use the last saved copy of the AUP file, then attach it so we can see it.
Please see how to attach files to forum posts.

Dear Gale

Thanks for your reply. There were sadly no recoverable versions just a note that the file was unrecognisable (attached). The data folder is over 10gb as it’s a 6 hour long recording.

Many thanks for your help.


Unfortunately the crash destroyed the AUP file. It is just 1 MB of zero data.

Look in Users<your username>\AppData\Roaming\Audacity\AutoSave to make sure there is no TEMP file from about the time of the crash. To check, type:


into the Explorer address bar then press ENTER on your keyboard.

If there is a TEMP file you could rename it to .AUTOSAVE extension then see if restarting Audacity can recover the project

If not and you still want to try to recover the recording you have to follow along with Basically use xplorer2 Pro or Ultimate to rename the temp files in timestamp order then use the 1.2 Recovery Utility to create new WAV files from the timesorted temp files.

You can’t play or export WAV files larger than 4 GB and 1.2 Recovery Utility can baulk on recovering too many files at once. So I suggest you recover no more than six d* folders from the Audacity temp folder at a time.

This means you will have to create a number of WAV files of about 1.5 GB each, then drag them into Audacity to reassemble the recording.


Thanks a lot Gale. You sure know your stuff- hope I can work it out. cheers
